Hello all;
I am have a PB 11.2 component running on EAServer 5.2 server, which is used to fetch and forward PDF reports to a .jsp webpage on our website. The PB component gets its data from a .NET Web Service, which arrives in the form of two byte arrays. The report generally works; however, from time to time, esp. when the jagsrv.exe is using a lot of memory (but not always) the data never arrives; that is, the NVO which should be populated with the data, does not receive the two byte arrays. In fact, it receives nothing at all.
The Web Service is definitely working correctly; I sniffed the network with WireShark, and discovered that the entire PDF, from the beginning XML tag to the end, is arriving at our EAServer correctly. The question is, why does the PB Component fail to receive the data?

ls_errors = "Unknown runtime error when invoking the web service " + is_webservice_name + "." + e3.Text
return -1
------------ Code snippet ends --------------------------------------------------------------------
inv_cst_return_results is a non-visual object with properties of two byte arrays, ib_pdf1[] and ib_pdf2[], and a string is_error_msg
inv_conn is an instance variable of type soapconnection
The failures are reported by an email which basically says the call to the function failed. None of the error messages inside the function are returned.
I would appreciate any advice that you might be able to offer.
thanks
